Pirate webcasts and unlicensed video footage of the Sydney 2000 Olympiad have been removed from several websites, according to the International Olympic Committee (IOC).
Only one website - US television network NBC's nbcolympics.com - has the rights to show video footage of Olympic action. Other websites are obliged to rely on text, still pictures and either pre-race or post-race audio and video interviews.
During the event, which runs from 15 September to 1 October, Datops, a French-based multi-lingual content analyst, is monitoring an estimated 24,000 websites for the IOC. The firm is checking what type of coverage the Sydney 2000 games is receiving.
So far, around a dozen culprits have been fingered, according to the IOC.
Although not naming names, the Committee said that many of the unauthorised clips were shown by websites which hold broadcasting rights, but which were confused as to exactly what could be legally shown online. This leaves only a handful of cases of pirate webcasts.
The IOC has been fiercely protective of the Olympics trademark, and this has been extended to the internet. In July, it filed the biggest cyber-squatting lawsuit to date in the US, accusing some 1800 registered domain names of misusing Olympic trademarks.
Illegal webcasts were expected by some because of the low cost of web cameras and restrictive broadcasting rights preventing cross-border transmission. This has led to time delays in showing events in some countries.
Separately, two spoof websites, which closely reproduce the design of the official olympics2000.com site, remain on the web. Both silly2000.com and shame2000.com satirise the official website mercilessly.
